Just days after completing their first tour without original bassist Kim Deal, the resurgent Pixies apparently have decided to part ways with her touring replacement, Kim Shattuck of The Muffs, who took to both Facebook and Twitter tonight to announce she was “super disappointed to learn that my time with the Pixies ended today.”

Mike Peters last week addressed his departure from Big Country, thanking both the band and its fans “for a wonderful four years” without offering any reason for his split with the reunited group — which itself only has revealed to fans that “Big Country and Mike will now be parting ways” as it continues on as a four-piece.

In the fall of 2010, the surviving members of Big Country regrouped, tapped Mike Peters of The Alarm to fill in for late frontman Stuart Adamson and proceeded to tour the world, and record and release a new album called The Journey. Three years later, though, Peters is out of the band.

The Violent Femmes have only played a handful of shows since reuniting this past April, but the band’s already experienced a major lineup shake-up: Drummer Victor DeLorenzo — who promised the band’s Coachella reunion would be a “monstrous thing of beauty” — is out, replaced by Brian Vigilone of The Dresden Dolls.

The Pixies this morning announced that bassist Kim Deal — who has spent much of this year touring with the reunited Last Splash-era lineup of The Breeders — has left the band , and, in a statement attributed to Black Francis, Joey Santiago and David Lovering, say “we will always consider her a member of the Pixies.”

Saying “my barnstorming days have come to an end,” Keith Strickland — a founding member of The B-52’s who switched from drums to guitar following the 1985 death of Ricky Wilson — today announced that he’ll no longer tour with the 35-year-old Athens, Ga., party band, although he’ll remain a member.

Bassist Tony Butler — who joined Big Country prior to the recording of its 1982 debut single ‘Harvest Home’ — announced this past weekend that he’s leaving the recently reunited band, writing in a message to fans that ‘after 32 years of incredible highs and a very tragic low, I feel that now is the time to look to new horizons.’

In a cryptic tweet late Sunday night, Jane’s Addiction frontman Perry Farrell hinted that ex-Guns N’ Roses member Duff McKagan — who joined the alt-rockers earlier this year to replace on-again, off-again bassist Eric Avery — may have parted ways with the volatile band.

Andy Rourke of The Smiths is no longer part of the Manchester triple-bass supergroup Freebass, which also features Peter Hook of New Order and Gary ‘Mani’ Mounfield of The Stone Roses, according to a note posted on the band’s website.

After just a year behind the kit, Social Distortion announced Monday that drummer Adam ‘Atom’ Willard — who also plays with blink-182’s Tom DeLonge in Angels & Airwaves — is leaving the long-running L.A. punk act.
